We report for the first time, to the best of our knowledge, a simple single pixel imaging (SPI) scheme with high singalto- noise ratio (SNR) in an entire THz frequency region (1 - 15 THz) by employing a thin metallic ring with a series of random masks directly perforated, that is a metallic randon ring'. This SPI scheme allows us to reconstruct highresolution images (320 x 320 pixels), and it offers potentially advanced THz imaging technologies, such as non-invasive assignment of biomaterials.
